2.Main Features of Sodium Hydrosulfite:

It is a versatile chemical that's used in the manufacture of a variety of products we all use every day, 

from photographic film to wine; from fine writing papers to leather goods; from colored fabrics to metal recovery.

While the applications for this chemical workhorse are as vast and as varied as the industries that use it, 

in most cases, sodium hydrosulfite performs one of the following three roles:

1) As reducing agent, hydrosulfite chemically reduces othercomponents by donating an electron or electrons

2) As sulfonating agent, hydrosulfite adds sulfur to another chemical compound

3) As cation source, hydrosulfite adds a cation, or sodium, to a product system

Q:Inorganic salts are not nutritious
Nutritional substances are sugar protein fat three nutrients
Q:What is the time when the maximum number of inorganic salts is needed
Seedling stage requires the largest amount of inorganic salts, because the seedling period is to lay the foundation for the growth period, in the strong growth period is mainly composed of synthetic organic matter.
Q:What is the inorganic salt
The main sources of various inorganic salts and the lack of the main performance (1) sodium sodium is the main ingredient of salt.China's nutrition society recommended adults over 18 years of age sodium intake of 2.2 grams per day, the elderly should take light food Sodium is commonly found in a variety of foods. The main sources of sodium are sodium, soy sauce, pickled foods, smoked foods, salty foods, etc. (2 Calcium is an important part of bone. Disease, osteoporosis, etc .. China Nutrition Society recommended adults aged 18-50 adult calcium intake of 800 mg per day; 50 years of age in the elderly 1000 mg.General calcium-rich foods are milk, yogurt, Oatmeal, sea cucumber, shrimp, wheat, soybean meal, soy products, lily, etc. (3) magnesium is the necessary elements to maintain the structure and function of bone cells.Magnesium deficiency can lead to nervous tension, emotional instability, muscle tremor and so on. (4) Phosphorus is an important part of the composition of bones and teeth. (4) Phosphorus is an important component of bone and teeth. (4) Phosphorus is an important component of bone and teeth. Severe phosphorus deficiency can lead to anorexia, anemia, etc. China Nutrition Society recommended adults over 18 years of age the appropriate intake of phosphorus is 700 mg. Common phosphorus-containing foods are lean meat, eggs, milk, animal offal, kelp, Nuts, coarse grains. (5) Iron is the most content of trace elements in the human body, iron and the human body's life and its health are closely related to iron deficiency will lead to iron deficiency anemia, immunity decreased. China Nutrition Society recommended 50 years old More than men's or women's iron daily intake of 715 mg. Common iron-rich foods are animal liver, kidney, caviar, lean meat, potatoes, wheat bran.
Q:Do inorganic mercury salts bioaccumulate?
Yes they do bioaccumulate. Mercury builds up for years and years, and eventually sits in a residue of pure mercury. - JJ
Q:Will a potassium ion from the inorganic salt KBr attach to NH2 at the end of a carbon chain?
The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.
Q:Cells are composed of water and inorganic salts or by organic matter and none
There are, but the water accounted for most of the inorganic salt to maintain cell acid and alkali balance;
Q:During the different periods of plant growth, the amount of water and inorganic salt required is different.
Plant life, although the need for a variety of inorganic salts, but different plants on the various types of inorganic salt requirements are different, such as cabbage, spinach and other human needs leaves of vegetables need nitrogen containing inorganic salts, tomato, peanuts need phosphorus Of the inorganic salt and more, sweet potatoes, potatoes need potassium-containing inorganic salts; the same plant with the growth period of the different requirements of inorganic salts are not the same, for example, plants in the seedling period requires nitrogenous inorganic salts , In the flowering, the results of the period of time need more phosphorus-containing inorganic salts. Therefore, different plants and the same plant growth period, the need for inorganic salts are different. So the answer is: different; different
Q:Several inorganic salts are lacking in symptoms and food sources
Ingredients of iodine-containing inorganic salts (trace): seaweed, jellyfish, corn, mussels, etc.
Q:what is the function of the organic part of bone matrix?of the inorganic part(bone salts)?
The organic part is where blood cells are manufactured. The inorganic part is for structural strength
Q:What is the relationship between electronegativity and the solubility of a inorganic salts?
The higher the electronegativity, the stronger the acid would be... Therefore it would be more soluble. take NaCl (common table salt) as an example. The difference between Na's electronegativity and Cl's electronegativity is very high so NaCl is a very soluble salt. The only exception is HF - it is a weak acid - it dissociates very weakly because O-H bonds cannot break H-F bonds which are very strong.
